.To ALLA' WHOM'IT MAY ooNeERg Be it known thatlI, EDWABDA. E. .OLMBTEAD,.of the city, coulliti'y, land State' ot'- NewYork, have,:inventedl a new and useful ihrprovementinftailroad Sweepers; t and 1 do herebydeclare'that thefollowing is a full,'elfaln,;

G are the brooms, which are attached tofand operated by the shaft to the inner endof which is attached a bevel gear-wheel, I, the teeth- 'of'which mesh in to the'teeth the 'bevel gear-wheel J attached to the axle B.v Kis a. frame, .surrounding the bevel gearfwheels I 'aud J, andiliaving holes through it, through which pass the axle B and the brodni-shaft H, and whielisfopmatlrahearingjorthe-inuenendgof said brotmi-shaftiv Y, The"frslnell keeps thegear-,wheels I1 and Jfiliv propenoperating 'posioxthfrespeet-.tf'eaoh other,howe'ver1 nu'eh the broom may-beq'alsferlforflowered; M and areitixe levers byme'ans of which the broom is raised and ,-lowered..'.. The levers L and M- are made of exactlythe same-lengthfsofthat when their inner ends are raised or lowered the same distanee', the ends of Athe broom-'shaft H will be raised or loweredeqhally. '.llhe levers L' and -Mjare pivoted to supports N upon the upper side o f the platform A, and th'eir inner-ends are pivoted to each ,other andtoablock or stirrup, O, Jvorliingin" the slotted support P. The pivoting-pin, by whioh the levers L and M are. pivoted to each otherA and to the I' block 0, passes through slots in the ends ofthe said levers, and also throughvertical slots '-in the supportR-so that all the said parts may be kept in their proper relative'po'sitions-while being raised and' lowered. "The'inner ends ot' the levers L and M are raised andlos'vered.' to adjust th'p-ostio of the broom, by niens of a hailxd-serewg" Q, passing ,down through a stationary nut formed in or attached to the upper end'of the support P, and 'itsvv lower end isgswifvelled'tothb bloekO, to'whichthe'ends of the levers'L audMfare pvoted. The outer` en@ of the lever M is conneete'dby a rod, R, to the outer` end of the, shaft E, or to journaI-boxhof the outer end of said shaft. 4 The onter'endofthe lever-'L is connected by afrod,`S, to that end of ...the frame K in :which the bearings-of the shaft Hare formed. B nt as the frarnefK is pivoted to the axleB, raising o r'lowering the inner part of the said frame willchange the relative positions pf the bearings'of the twoends of the-shaft H, ea.usingA it to bind, and thus impeding its' working properly. To remedy this I form a .universal joi t,- T, in the shaft H, between'the frame K'aud thobroom 'G,.so that the said-shaft' may operate freely, howeverllmuch the end of 'the frame K may be raised or lowered.

I claim as new, anddesire'to'secure by'Letters Patent- 'The construction and arrangement of the'levers LM ofzltbe same length, their .iun'er ends slotted and pivoted togotheg'and to thestrrnp working vertical'lytinthe slotted support l?, and adjusted by' means of lthe hand-screw'Q, said levers near their` outer end s .pivoted supporter N upon the .platforml A, andtheir outer ends'lpvoted to the rlids R S, attached to the ends of the shaft K, respectively, wherebyl the' said. shaft' and broom'G are raised'or lowered, substantially. as herein set forth'for. the'npurpose specified.
